TECHNICAL FIELDThe present disclosure relates to a field of household appliances, more particularly to a steam valve for a cooking utensil and the cooking utensil.
BACKGROUNDIn the related art, a steam valve is an essential component of a cooking utensil. The steam valve is used to communicate an interior of the cooking utensil with an exterior of the cooking utensil, such that moisture inside the cooking utensil can be well evaporated when the cooking utensil is cooking rice, and meanwhile a buffering space can be provided for rice-water during a boiling stage when cooking rice. The higher the cooking power is and the more violent the boiling is, the sweeter the rice is. However, a problem caused by the high cooking power is that the rice-water is prone to spilling in the cooking process. The cooking power of the boiling stage is generally lowered in order to ensure that the rice-water does not spill during the boiling stage, which however influences operation efficiency of the cooking utensil, and is time-consuming.
SUMMARYThe present disclosure seeks to solve at least one of the problems existing in the related art. To this end, the present disclosure proposes a steam valve for a cooking utensil, which has advantages of a simple structure and good spill-proof performance.
